Study On Solution For Subsea Pipeline Integrity Management

Submarine pipeline integrity management is a new topic of research in recentyears around the world. For full life-cycle of the subsea pipeline, considering thecomplex factors in the pipeline life-cycle, using different methods and means to meetpipeline safety requirement, and ensure that the price paid for the minimum. Thispaper studies the integrity of management theory and methods, the research results areused for risk identification, management and control of the Hangzhou Bay submarinepipeline. The research has important theoretical and engineering significance.Hangzhou Bay submarine pipeline south from Ningbo Daxie Island, north acrossthe Hangzhou Bay up to Pinghu Baishawan Pumping Station.It is not only the firstpipeline across the Yangtze River. And also the largest and longest Subsea pipeline inthe Gulf of strong tidal District.It bears the important task of transportation of crudeoil across the Yangtze River Delta, with an important strategic significance.Theenvironment of the submarine pipeline is strong tidal zone Gulf of high risk, urgenttide, tidal range, the transmission medium is a high-sulfur Middle East crude oil.Insuch a complex and harsh service environment, safe and stable operation of thesubmarine pipeline is the most important issue to consider.This topic is based on the Hangzhou Bay seabed pipeline running status quo,much-needed demand for safe operation of the submarine pipeline from the PipelineStorage and Transportation Company. Below list the four aspects of the subseapipeline integrity management work. A. Subsea pipeline integrity managementinformation base platform; B. pipeline outside risk analysis module; C. Inside riskanalysis module for the pipeline; D. External application modules.Innovative research in this article as shown: A, through the implementation ofthe submarine pipeline integrity to enhance and strengthen the level of safety inproduction management. B. submarine pipeline integrity management to consider thereliability of the submarine pipeline system, the identification and evaluation of keyparts of the risk of defects and clear defects in the sources of risk, grade, and thefailure mechanism, to determine the effective inspection methods and frequency, takethe appropriate management strategies to ensure that during service in a good state ofoperation. C. Subsea pipeline integrity management can optimize undersea pipingdesign, construction, and maintenance management to provide effective support. D.Submarine pipeline integrity management can achieve the full life cycle management of the Hangzhou Bay submarine pipeline.E. Hangzhou Bay submarine pipelineintegrity management system tools development at home and abroad the first truesense of the subsea pipeline integrity management tools, and innovative way make thereliability, availability, maintainability concept applied to pipeline productionoperations run decision-making aspects.Through the implementation of the submarine pipeline integrity management,subsea pipeline design, construction, production testing, repair, maintenance data cancollect together, entry into the system, the establishment of a comprehensive database,centralized management. Submarine pipeline management, testing, maintenance,repair and other services to provide accurate system related to historical data, tofacilitate production management. It can able to quickly provide relevant informationfor the emergency repair, auxiliary emergency rescue and problem analysis, programdevelopment and program implementation. It can also provide information and testingfor oilfield expansion, transformation, and location-based services.
